ok if you look at my original post you will see that the url is clickable. I did not put the <a href=> part in it but simply wrote out the url. How did you guys get that to become clickable as it is on a line with something else.

The left-hand side of the regex basically pulls out what we think is a URL. The right-hand side evaluate some Perl code to try and remove any non-URL junk at the end of the URL. For instance, if the string held "Visit my web site at http://www.foo.com/~me.", we wouldn't want to keep that . in the link, because it would foul things up. I'm not sure my approach is a spectacular one, but it should work well at not including things in the URL section that it shouldn't.
